This map shows the geographical regions of England shaded in teal, with internal borders highlighted in light gray. The visualization uses a React component structure with D3 v7’s `geoNaturalEarth1` projection and `geoPath` to render the SVG paths. Region polygons and interior boundaries are derived from a TopoJSON dataset via `topojson.feature` and `topojson.mesh`. The map displays static region shapes without interactive or animated elements, relying on React state management to load the data asynchronously.
